SUBJECT:
NRC INSPECTION - RADI0 ANALYTICAL SAMPLING AND RADIOLOGICAL SURVEY RESULTS OF THE NORTHEAST OHIO REGIONAL SEWER DISTRICT SOUTHERLY WASTEWATER TREATMENT PLANT AND EASTERLY WASTEWATER TREATMENT PLANT (REPORT NO. 999-90003/94060(DRSS))
Dear Mr. Odeal:
This refers to the special inspection conducted by Mr. Michael Kurth of this office from October 31 through December 5,1994, of the Southerly Wastewater Treatment Plant (SWTP) and Easterly Wastewater Treatment Plant (EWTP). The inspection was prompted by the positive identification of cobalt-60 in a filter cake (sludge) sample collected by the Northeast Ohio Regional Sewer !
District (NE0RSD) personnel on September 22, 1994, at the SWTP. The NRC ;
2 inspector, working with the assistance of the Ohio Department of Health l personnel, collected sewer waste water, sludge, and ash samples for radiological analysis and performed surveys of SWTP and EWTP treatment process areas.
li.e enclosed copy of our inspection report identSies the areas surveyed during the inspection. The inspection consisted of beta / gamma surveys and the collection and radiological analysis of sewer waste water, sludge, and ash samples.
As a result of the inspection, we have no health and safety concerns. Surveys conducted during the inspection did not identify any areas of elevated exposure rates within the SWTP and EWTP treatment process areas. No cobalt-60 concentrations were identified above the minimum detectable levels in the 81 samples collected from the SWTP and the EWTP treatment process areas.
However, trace amounts of iodine-131 ranging from 0.7 to 1.4 picocuries per gram (pCi/g) were identified in five samples taken at the SWTP on November 1, 1994. Also, the SWTP incinerator ash samples (3 per day) were identified as containing trace quantities of: bery111um-7 ranging from 12 to 32 pCi/g; thallium-201 ranging from 12 to 75.7 pCi/g; and radium-226 ranging from 3 to 10 pCi/g. The concentrations of iodine-131 and bery11ium-7 identified in the SWTP samples were below the 10 CFR Part 20.2003, " Disposal for Release into Sanitary Sewerage" limits.
The State of Ohio regulates the use of accelerator produced radionuclides and naturally occurring radionuclides. Therefore, thallium-201 (accelerator produced) and radium-226 (naturally occurring) are considered to be regulated by the State of Ohio. A copy of this report will be issued to the Ohio Department of Health for their review of these findings.
